tionin which a single batch of molten glass is spread against a supporting surface to sheet form with wire incorporated within it; and the objects of my improvements are to render this onepour operation. of greater practical value than it has heretofore been, by avoiding certain difiicultics in the prior practice.

in the accompanying drawings which form part of this specification, Figure 1 is a view in longitudinal vertical. section of my improved m chine; Fig. 2 is a plan View of this machine, showing one feature or element thereof in modified form Fig. 3 shows in elevation a detail of the machine as illustrated in Fig. 2; Fig. 4; is a view in cross section oi one of the rolls of the machine of Figs. 1 and 2; Fig. 5 is a view correspond ing to Fig. 1 and illustrating amodification of another feature or element thereof; Fig. 6 shows in detail the application of the modification separately illustrated in Fig. 3 to the machine in the form shown in F ig. 5; and Fig. 7 shows in longitudinal vertical section a modification of still another fea ture or element oi'the machine of Fig- 1.

Parts which are repeated in the several ng'ures hear the same reference numerals in each case. i Referring first to Fig. l of the drawings, the machine will be seen to include a form ing surface, here shown as a horizontally extending table top, 1. Means are shown, coiiperating' with this table-top, to spread a batch of'molten glass deposited thereon to sheet form. andto incorporate therein a web of wire. The means preferably employed consist of two rolls 2 and 3, organized with the table to traverse the table from end to end. To this end the rolls are preferably -mounted in stationary housings While the top upon which the sheet is formed.

Traveling immediately behind roll 2 is roll 3. lit is a corrugated roll, and its purpose is, by virtue .of its corrugations, to sink into the body of the layer a the web of wire B with which its surface is covered at the time when the layer of glass (5 in the operation of the ma chine comes beneath it.

In addition to means for spreading; the sheet and sinking the wire into it, the machine includes means for smoothing the surface of the wire-containing sheet I) which passes from beneath the corrugated roll 3. The means shown in Fig. l for accomplishing this end consists, primarily, in the roll t, properly organized with the table top and the forming rolls already described, and it also is preferably a positively driven roll. Cotiperating to the same end-c". e. the smoothing of the surface of the wire-containing sheet Z) is a gas pipe 8 from whose nozzle a flame is projected upon the suriface of the sheet Z), as it advances (or as, in conthis stream of flame, by its presence. ex-

cludes the air from access to the incandes cent wire (to the extent that it is uninclosed by glass) and prevents blackening of the wire.

The feature of invention which ll shall first describe in detail relates to the corrugated roll 3, employed for sinking the wire into the glass until it takes definite and predetermined position relative to th.: table 11 have found it advantageous to corrugatc roll 3 in the manner which is indicated in Figs. 2 and 4. It will there be seen that the corrugations of the roll, instead of extending in annular grooves around the roll body, wind spirally over it, extending longitudinally of the roll well as laterally. And further, the corrugations are out out so deep that, in the operation of the machine. the glass entering the corrugations does not completely lill them. and the surface of the protrusions of glass entering the corruga- T ll lli

The batch of molten A teein'edl upon the table it is spreacl to layer form beneath the roll E2, the nioistenn'ig of the roll effect ing 21 Superior condition of the surface of the layer spread beneath it. This layer so sprenri then comes beneath the corrugated. wire-embedding roll, anti this Wire-embectrling roll by virtue of the (lepth and shape of the corrugations and the cooperating ten sion roll, places the Wire more definitely in the sheet and leaves the surface in more suit able condition for further smoothing then is commonly the practice.

TheJ-surfoce is bus regenerated or softenecl, so thet the smoothing moons then acting upon it will bring it to better condition than has heretofore been obtained in such Wire gloss machines; and, at the some time, so much of the Wire as is exposed is protectecl from the oxidizing offeet of the air.

As to the corrugated rolls and the method of operation practised in their use, I have made thot portion of my invention the subject of o divisional application, Serial No. 735,126, filed. December 5, 1912; as to certain features of the machine here describecl onrl its mode of operntioin l have incorporated them in an application which is to that extent a. continuation of this, Serial No: 796,931, filed October 23, 1913.

I claim herein as my invention:

in o machine for making Wire-glass the combination of n forming surface, n roll cooperating therewith to incorporate an inlzty of Wire in o loyer of gloss, o, smoothing roll cooperating with said forming surface, arranged adjacent the roll firet named and forming a pocket of Which the layer of glass in the course of formation is the bottom and a gen nozzle directed into such pocket.
